Book Description
Myrtaceae is the ninth largest flowering plant family; it is economically important in the production of timber, gums, essential oils, fruits and spices, and contains many commonly cultivated ornamentals. The family is particularly rich in large genera, often found in some of the world's most threatened ecosystems, where their fruits comprise an important part of the diet of primates and birds. The similarity of Myrtaceae species is high, and its taxonomic and nomenclatural history is complex, resulting in notorious difficulties in basic identification, inventory compilation and floristic treatment. The World Checklist of Myrtaceae is a much needed work that lists all validly published names in the family, providing the source of their publication and indicating which names are currently accepted and which are synonyms. It will be respected as the standard nomenclatural reference for further research into this important family.

Book Description
This book came about as a result of a review I had written earlier on fea tures of cellular changes occurring during anuran metamorphosis. Only a limited treatment of this subject was possible in such a circumscribed work and only specific examples of organic change were dealt with. Thus the sins of omission weighed heavily, for so much information could not be included to provide a more comprehensive and authenticated account of the elaborate, complex, and far-reaching changes that an aquatic larva undergoes to become a terrestrial froglet. A good deal of my working life has been spent investigating amphib ians, especially their larval developmental morphology during metamor phosis, first at the level of light microscopy and in later years by electronmicroscopy. Initially I was particularly concerned with morpho logical homologies of a variety of larval structures, such as the cranial and pharyngeal skeleton and the nerves and musculature, in order to learn more about amphibian phylogeny, for during my pre-and early postgrad uate years G. R. Beer and D. M. S. Watson inspired an undying interest in and respect for vertebrate comparative anatomy. However, it now seems to be that amphibian phylogenetic relationships are best dealt with by the paleontologists, so ably demonstrated by D. M. S. Watson and A. S. Romer and the contemporary enthusiasts in this field like A. L. Panchen, R. L. Carroll, E. Jarvik, and K. S. Thompson among a host of others, particularly in the USA.

Book Description
Until now, information on mammals in South Asia has never been brought together on a single platform providing all‐inclusive knowledge on the subject. This book is the most up‐to‐date comprehensive resource on the mammalian diversity of South Asia. It offers information on the diversity, distribution and status of 504 species of terrestrial and aquatic mammals found in Afghanistan, Bangladesh, Bhutan, India, Maldives, Nepal, Pakistan and Sri Lanka. This work is unique being the first of its kind that deals with diversity and distribution at the subspecies level. The book is divided in to three chapters. Chapter 1 introduces the subject and takes off from the recent works on mammals at the global level, provides an historical perspective on mammal studies in South Asia and concludes with a note on recent phylogenetic changes at supraordinal levels. Chapter 2 summarizes the information on the diversity of South Asian Mammals, provides analysis by country of mammalian diversity (supported by data in tabular form) dealing with species richness, endemism and possibly occurring species, separate analysis for each country with details on endemic and threatened species, extinct mammals, domestic mammals, and finally the IUCN status of mammals with special emphasis on threatened mammals. Chapter 3 is a comprehensive checklist that provides information on each species, including its scientific name, type details, standardized English name, synonyms, subspecies, distribution and comments on taxonomic status. Country‐wise listings and analysis of species richness with emphasis on subspecies distribution Most of the analysis is supported by data in tabular forms for better understanding Notes on extinct and domesticated mammals as well as their IUCN Red List Status with criteria for such status A very comprehensive bibliography that would help readers track down specific literature ​
